QuickTime for Windows: mov playback video choppy when accessed from NAS device

    I have a 2.5GB 640x480 30fps mov file that I created with QT Pro v6.x
    that plays very choppy video at 2fps (average) when accessed from my
    externally attached WD Netcenter NAS network drive. The sound however
    is fine. When I play this .mov in QT when it resides locally on my Dell
    Inspiron 8600 40GB internal HDD it plays fine - nice and smooth - both
    sound and video are good.

    I'm wondering if this might be due to the speed limitations of the
    network drive over the LAN (but I'd be suprised, it's new) or the
    network drive device's CIFS file system that it uses.

    Interestingly, this issue of choppy video is similar when the mov file
    is accessed from the CD/DVD drive (burned copy), which points me back
    to possibly an access speed issue (it has to be slower than the local
    HDD), although I think the CD/DVD uses CDFS which is another file
    system format other than the standard NTFS or FAT.

    Is there anything that I can do to: A.) Adjust the frame rate in the
    video (it shows it in preferences/QT settings, but is unchangeable);
    B.) Buffer the video stream over the LAN as you would do over the www
    so that video is buffered before and while it plays; c.) Anything else.

    I'm desperate to get this working because the files need to reside on
    the NAS device as they are too big and too many for the local drive.
    They also need to be played from there as it takes too long and is too
    tedious to copy locally everytime it will be played.

    Alternatively, is there another mov player that would be more efficient
    in buffering a video stream from a sluggish device?
